unlocked phone
After my unlocked Samsung phone broke, I got a new unlocked Iphone 6 but it doesn't allow me to use the wifi. When I turn it on, it is asking me to put in SIM card into the phone. I usually depend on wifi to communicate with friends with unlocked phone in the US, and have a prepaid sim card in my homeland. But for this iphone, it is not letting me do so. I thought that we didn't need a SIM card to just use the wifi because that is what I did for my Samsung phone. Do I have to get a SIM card for a new phone even though I dont need any phone calling, text, and 4G?
